This video is a step by step guide on how to properly install our 40 gallon refueling tank. The 40 gallon refueler is compatible with multiple vehicles, and will even fit smaller trucks like the Dodge Dakota, Toyota Tacoma, Ford Ranger, Nissan Frontier, and GM Colorado/Canyon.

When it comes to in-bed refueling tanks, it’s hard to know what’s legal and what’s not. With a Transfer Flow refueling tank, you don’t have to guess! Our refueling tanks are Department of Transportation (DOT) legal to carry and transfer gas, diesel, ethanol, methanol, kerosene and jet fuel in all 50 U.S. states. Having a DOT legal refueling tank from Transfer Flow means you won’t get red tagged and fined by your Highway Patrol for carrying an illegal fuel tank in the bed of your truck.

(Chico, CA) Introducing Transfer Flow's 40-gallon in-bed auxiliary fuel tank system—the fuel tank with the small footprint, but maximum versatility. The unique design of the 40 gallon fuel tank makes it compatible with almost any full-size diesel truck, including half ton pickups, trucks with utility beds, RamBox® equipped trucks, or those with a factory installed 5th wheel prep package. Because of its low height, it also fits under most standard tonneau bed covers!

The Hauler is based on customer requests for more gallons available in a commercial-grade tank. Available for 2000 – 2015 full-size Dodge Ram, Ford and GM diesel pickups with eight foot beds, this fuel tank is constructed of bright aluminum diamond plate and mill finish aluminum, and is fully baffled to minimize fuel sloshing and maximize tank strength. The fuel tank can be powder coated black as an upgrade.

If you’re planning any riding adventure, you’ll also be using a little fuel, and that often means toting fuel cans or jugs along. We’ve never really liked hauling a potential fire bomb in the back of our truck, especially when the sun is constantly causing the jugs to expand and vapors to escape. There had to be a more secure, safer way to transport fuel, and recently we found one.
